Hello,
I acquired nucore and an ASUS PH861-Mlx mother board, everything is fine
installation went more or less fine, i had problems due to outdated version of UBUNTU versus a recent motherboard version, like problems on recognizing sata disc and Ethernet controller, but after scratching a lot in the internet I could fix these two problems, now I have a major problem and it seems that the solution is not an easy one, I can not put audio working!, it seems that ubuntu does not support the audio device, I need advice here please, another motherboard or an external sound card? if external sound card, which one?

Try the audio patch above. It's possible that it will resolve your issue. Sometimes it takes a little digging and possibly building a driver. I don't believe we've ever had a user who couldn't resolve a sound driver issue.

Thanks Chuck, but I think you forgot something, a link or an attachment maybe...
meanwhile I solved the problem by using a pci audio card (creative Audigy ZS), I had to change ASUS P8H61-Mlx for ASUS P8H61 which have PCI slots... it seems that most of asus cards uses the unsupported (by alsa drivers) alc887 audio codec.
